| Abstract | ||
| The advantages of additive manufacturing technology have a big influence on various industrial applications. The use of 3D printing technology facilitates the creation of complex, lightweight geometric designs with increased robustness. This study focuses on the effect of recommended parameters of printing like raster angle (45°/-45°, 0°/90°), layer thickness (0.2, 0.15, and 0.1 mm), and infill pattern (cross 3D and gyroid) on the tensile strength and other mechanical properties of the open-hole test. The specimens were fabricated utilizing Fused Filament Fabrication (FFF) technology using Polylactic Acid (PLA) thermoplastic material by a 3D printer machine in a standard dimension. According to the test results, the tensile strength and other mechanical properties were strongly impacted by the parameters. The best results were obtained with a 45/-45 raster angle, 0.1 mm layer thickness, and a gyroid infill pattern, and the tensile strength as a result was 27.6 MPa, strain was 8.24%, and elongation was 12.35 mm. | ||
